三氯一茂(或甲茂)钛化合物的合成已有文献报导.曾用过的合成方法主要有:Cp_2TiCl_2(MeCp_2TiCl_2)与过量的 TiCl_4发生岐化反应;Cp_2TiCl_2在光照射下与 Cl_2反应;或 TiCl_4与 CpSiMe_3反应等。这些合成方法存在着,反应条件较难控制,反应时间较长和产率较低或原料较难得等缺点。1989年 Kailash 等人用 Cp_2TiCl_2(MeCp_2TiCl_2)与 SO_2Cl_2在 SOCl_2中回流3小时制得三氯一茂钛或三氯一甲茂钛。我们在此方 The synthesis of trichlorocene (or thio) titanium compounds has been reported in the literature.It has been used in the synthesis of the main methods are: Cp_2TiCl_2 (MeCp_2TiCl_2) with excessive TiCl_4 occurred disproportionation reaction; Cp_2TiCl_2 under light irradiation with Cl_2; or TiCl_4 With CpSiMe_3 reaction and so on. These synthetic methods exist, the reaction conditions are difficult to control, the reaction time is longer and the yield is low or raw materials more difficult shortcomings. In 1989 Kailash et al. Used Cp_2TiCl_2 (MeCp_2TiCl_2) and SO_2Cl_2 to reflux in SOCl_2 for 3 hours to prepare trichloro titanocene or trichloro-titanocene. We are here
